MATH221 Final Exam Study Guide
YOU MAY WANT TO PRINT THIS GUIDE.

1. The Final Exam is open book and open notes. The maximum time you can spend in the exam is 3
hours, 30 minutes. If you have not clicked the Submit for Grading button by then, you will be exited from
the exam automatically. In the Final Exam environment, the Windows clipboard is disabled, so you will
not be able to copy exam questions or answers to or from other applications.

2. The exam automatically saves answers after you click to the next question. This helps prevent
connection timeouts that might occur with certain Internet service providers and also minimizes lost
answers in the event of connection problems. If your Internet connection does break, when you
reconnect, you will normally be able to get back into your Final Exam without any trouble. Remember,
though, that the exam timer continues to run while students are disconnected, so students should try to
log in again as quickly as possible. The Help Desk cannot grant any student additional time on the exam.

3. See the Syllabus section "Due Dates for Assignments & Exams" for due date information.

4. Reminders
 You will only be able to enter your online Final Exam one time.
 If you lose your Internet connection during your Final Exam, log on again and try to access it. If
you are unable to enter the Final Exam, first contact the Help Desk and then your instructor.
 You will always be able to see the time remaining in the Final Exam.

5. Assessments With Multiple Pages
